A 1 unit per 2; acre density applied to the xeric scrub east of the St. Sebastian River (with clustering requirements) provides reasonable protection to the scrub and river, in combination with the 1 unit per 40 acre density (applying to the 125+ acres of wetlands) and a riverlwetland setback buffer. The number of potential development units within the 300 acres of xeric scrub on the east side of the river is further reduced -when one accounts for the approximately 125 acres of scrub The Indian River County Soil Survey identifies "Orsino -fine sand, 0 to 5 per( slopes" as the soil associated with xeric. scrub east of the St. Sebastian Ri` Relative to other soils in the county, Orsino fine sand is one of the better soils septic tank absorption fields, with moderate limitations. Soil modifications; combination with setback requirements from the river, would minimize ecolog impacts associated with septic systems. This issue will become moot over time on east side of the river, however, as public sewer will completely serve the area by year 2010 (see the Sanitary Sewer Sub -Element for reference information). A conservation designation on the west side of the St. Sebastian River to pro` resource protection would cover approximately 600 acres of xeric ser approximately 150 acres of wetlands border the river on the west side in unincorporated county as well. The xeric scrub and associated wetlands on the v is outside of the county's Urban Service Area (USA). At a 1 unit per 22 etre density, the venin scrub in this area would have a nntential fnr a maximum of approximately 240 residential units. In that the area is outside of the USA, individual wells and septic systems would be associated with the residential units. The county soil survey identifies "Electra sand, 0 to 5 percent slopes" as the soil associated with the scrub community west of the St. Sebastian River. The soil is classified as "somewhat poorly drained", and in its unaltered state the soil has severe limitations for septic suitability—. However, even with its limitations, local SCS soils scientists identify Electra sand as one of the better soils in indian River County for septic tank absorptions ie s an m ca e that all of its limitations-= be overcome. Adequate amounts of suitable fill material would increase the effective depth to the water table and the restrictive layer and provide needed filtration. The risk of filtration problems can be reduced by maintaining maximum setbacks from the river and associated wetlands, and Ph can be raised in the immediate area of a septic tank to prevent corrosion to the concrete. The Solid Waste Sub -Element of the Comprehensive Plan substantially describes and analyzes hazardous waste management practices in Indian River County. The following points are summarized: - The County Utilities Department presently has limited storage facilities att e coup —ylaa—n filr of r eesidenti—generated-iazardous waste. This facility does not accept such waste from small quantity commercial or industrial generators. contract with private hazardous waste haulers for the disposal of waste materials. A future expansion of the storage facility at the landfill for temporary storage of hazardous materials is proposed. - There is apathy or ignorance regarding the impacts of improper hazardous waste disposal or illegal dumping in Indian River County, in that illegal dumping continues to be a problem. A program to educate the public concerning the economic and environmental impacts of such activities could help to address this matter. Also, an increase int e consequences of illegal dumping (ie -fine penalties) may help to deter such problems. -68.2- u\rlrlcompre SmeadSoft Reprint Date: Friday, August 23, 2013 - 12:00:07 - OfncialDocuments:626, Attachment Id 0, Page 9
